Question

The sum of the circumference and diameter of a circle is 116cm. Find its radius.​

Answer 1

Answer:

Given :

Circumference + Diameter =116 cm

Circumference =2πr

Diameter=2r

We can write,

2πr+2r=116

2r(π+1)=116

2r= 116/4.14

2r=28.0913

r=14 cm (approx)

Answer 2

Answer:

Approx =14 cm

Step-by-step explanation:

Given :

Circumference + Diameter =116 cm

Circumference =2πr

Diameter=2r

We can write,

2πr+2r=116

2r(π+1)=116

2r=4.14116

2r=28.0913

r=14 cm (approx)
